This lecture covers the historical development and applications of piezoelectric transducers, focusing on crystal resonators and SAW devices. It explains the equations and boundary conditions for resonators, the impedance measurements, resonance, anti-resonance, and acoustic power radiated by transducers. The lecture also delves into the impedance matching for maximal bandwidth and the importance of correct crystal orientation and polishing for high-frequency transducers.
